Real straight forward. Assuming power available from the fuse block and no wiring issues, there are just 2 permissives to satisfy :

1. Brakes not applied

2. Throttle at least 10% open

Schematic:





Also, to verify that the TCC will operate you don't even have to splice into the power lead. There should be a test connection (orange) under the dash.

It won't have anything connected to it, and should be between the fuse block and the steering column. Run a switched hot wire to it and play around with the TCC. You'll know if it works right away:

Thanks. I will check the fuses and then run a hot wire to that orange connector. It has been pretty cold the last couple of days so I will wait for a little warm up before diving into it.
